CHAPTER 12: DESCRIPTION OF PARAMETER SETTINGS

• These parameters are used to set the skip frequency of the VFD. But the frequency output is continuous. There is no limit for
the setting of these six parameters and can be used as required.
• These parameters are used to set the skip frequency of the VFD. But the frequency output is continuous. The limit of these six
parameters is 01-28 ³ 01-29 ³ 01-30 ³ 01-31 ³ 01-32 ³ 01-33. This function will be invalid when setting to 0.0.
• The skip frequencies are useful when a motor has vibration at a specific frequency bandwidth. By skipping this frequency, the
vibration will be avoided. It offers 3 zones for use.
• The setting of frequency command (F) can be set within the range of skip frequencies. At this moment, the output frequency
(H) will be limited by these settings.
• When accelerating/decelerating, the output frequency will still pass the range of skip frequencies.
• When the frequency is less than Fmin (Pr.01-07 or Pr.01-41), it will operate by this parameter.
• When it is set to 0, the VFD will be in waiting mode without voltage output from terminals U/V/W.
• When it is set to 1, it will execute DC brake by Vmin(Pr.01-08 and Pr.01-42) in V/F and SVC modes.
• When it is set to 2, the VFD will run by Fmin (Pr.01-07, Pr.01-41) and Vmin (Pr.01-08, Pr.01-42) in V/F and SVC modes.
• In V/F and SVC modes
